TAY - Big Creek at Taylor Ranch

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Biomark
General Operational Period: Year Round
Start Date: 7/1/2006 12:00 AM

Site currently consists of a Biomark IS1001-Master Controller, 12 IS1001 readers, 12 20 ft antennas. The antennas are arranged in tandem with each array containing 6 antenna spanning 120 ft with a distance of 45 ft between the arrays. Site has solar power, Hughes satellite modem and Campbell Scientific CS450L, CS107 environmental probes. From 2006 until October 2017, the site was located about 250 yards downstream of its current location, centered around the bridge at Taylor Ranch. It consisted of two FS1001M transcievers operating two arrays of six antennas each approximately 200 meters apart, spanning Big Creek above and below the bridge.

2011 1/1/2011 12:00 AM 1/1/2012 12:00 AM Antenna A1 removed on May 24 and replaced on August 27. Antennas B3 and B4 stopped operating on June 7; antenna B5 stopped on June 8; antenna B6 stopped on June 9; antenna B2 stopped on July 4 and antenna B1 stopped functioning on July 7. There was no detection on the lower array from July 7- Agusut 26, when all six antennas were replaced.
2010 1/1/2010 12:00 AM 1/1/2011 12:00 AM Activities at TAY were suspended between January 28 and March 17 due to power constraints. The antennas in each array were relocated during the August O&M check. In both arrays, the six antennas are configured in two rows of three antennas each, providing tandem coverage (~5 meters apart) of the right half of the stream. The antennas are to be repositioned to their previous locations, spanning the stream, in Spring, 2011.

2008 7/22/2008 5:00 PM 1/1/2009 12:00 AM The Taylor Ranch site was re-activated on July 22, 2008. Initially only the MUX antenna array above the bridge (A1-A6) was enabled.
2006 7/1/2006 12:00 AM 12/12/2006 12:00 AM First year of operation. Two antennas in the upstream array were damaged and taken out of service on or before October 6, 2006. An ice storm damaged most or all of the remaining antennas between Dec. 9-12, effectively ending interrogation activities.


Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.

Event Log Summary

Event Date Event Type Comments
9/14/2021 9:00:00 AM General

Replaced IS1001 nodes 01 through 0B. Node 0C was not replaced because the DOP run was too long for the amount of DOP cable on site. New DOP node 06 cable was spliced onto old DOP cable.

Installed a low voltage disconnect on the main circuit breaker to protect the batteries at the solar array.

9/18/2018 12:00:00 PM General Shed tag removed from Antenna 1. Node replaced on Antenna 7. Site is fully operational.
5/25/2018 6:00:00 AM General Node on Antenna 7 failed.
5/11/2018 8:00:00 PM General Shed tag on Antenna 1.
2/21/2018 4:00:00 PM SiteUp Solar panels (16) replaced. Site operational.
12/11/2017 6:00:00 PM SiteDown Site down due to solar power issues.
10/11/2017 10:26:00 AM SiteUp Big Creek Array (TAY) was shut down October 2-10 to remove the existing arrays to create a new tandem array using new equipment. The new site has been constructed approximately 250 yards upstream from where TAYA0 was originally. The new site is a tandem array consisting of six 20 feet Biomark HDPE antennas upstream and six 20 feet Biomark HDPE antennas downstream that are deployed 45 feet from each other. Each array spans the entire Big Creek at base flows. The solar array from TAYB0 was moved next to the original TAYA0 array to bolster the power needed to operate the new equipment. New batteries were also installed for the solar arrays TAY now utilizes a Biomark IS1001-Master Controller, 12-IS1001 readers, Hughes Satellite modem, and employs the original Campbell Scientific CS450L data logger. Environmental probes for air/water temperature and a pressure transcucer were also installed at the new site. The upstream array now contains antennas: 01, 02, 03, 04, 05, and 06. The downstream array contains antennas 07, 08, 09, 0A, 0B, and 0C.
8/1/2013 2:30:00 PM General A0 (upstream array) antenna 06 was replaced. Found crack in corner of antenna.
